Section 1 - Spectroradiometer
1. INTRODUCTION
This User Manual applies to the following SVC field-portable spectroradiometer products:
•
The HR-1024i covers the UV, Visible, and NIR wavelengths from 350 nm to 2500 nm. It uses 3
diffraction grating spectrometers with 1silicon and 2 InGaAs diode arrays. The silicon array has 512
discrete detectors and the InGaAs arrays each have 256 discrete detectors that provide the capability
to read 1024 spectral bands.
•
The HR-768i covers the UV, Visible, and NIR wavelengths from 350 nm to 2500 nm. It uses 3
diffraction grating spectrometers with 1silicon and 2 InGaAs diode arrays. The silicon array has 512
discrete detectors and the InGaAs arrays each have 128 discrete detectors that provide the capability
to read 768 spectral bands.
The spectroradiometer includes memory and a display for stand-alone operation as well as capability for
personal computer (PC) and personal data assistant (PDA) assisted operation. PC communications to the
instrument are available through its USB client port, a Bluetooth wireless connection, or via RS-232. A
PDA may control the instrument via a Bluetooth connection or via RS-232.
The instrument includes a second Bluetooth channel that may optionally communicate with an external
sensor suite (future development).
When operated in stand-alone mode, up to 1000 spectral readings can be stored in the instrument for
subsequent down loading and analysis using a PC. All spectroradiometer identification and calibration
information is stored on board, so there are no external files to manage.
The instrument contains an internal GPS device to record the latitude, longitude, and time of each spectral
reading.
This instrument is self contained and incorporates an easily replaceable battery called a SMARTPACK.
The battery chargers supplied with the instrument have the capability to charge the LI-Ion batteries from
line voltage with the AC adapter.
The computer based operation allows for real time data display and data analysis. Radiance and percent
reflectance are provided within the acquisition software. Stand-alone operation makes this same
information available for display on the instrument’s LCD (liquid crystal display), which is located on the
rear panel on the instrument.
A full range of options are available. These options include alternate foreoptics, fiber optic light guides,
irradiance spheres, cosine diffusers, Reflectance Probe, back packs, white reference panels, tripods and
other custom engineered field devices.

Foreoptic Options
Different foreoptics can be attached to provide different fields of view (FOV) to enable the instrument to
look at different size targets. Normally the target is at a distance of 1m from the optical element. See
section 3 item 1 for the field of view setup. Measurements can be taken at further distances but the target
size will be larger. The foreoptics are mounted in lens barrels or adapters that are secured to the unit by
hand using a threaded collar and are keyed to go in at the same clock angle to maintain consistent
radiometric readings. The following foreoptics are available:
(1) 4° nominal FOV lens (standard)
(2) 8° nominal FOV lens (optional)
(3) 14° nominal FOV lens (optional)

collar until hand tight point. Do not over-tighten.
Battery Pack
The instrument’s Battery Pack provides power for portable operation. The battery pack installs via
dovetail slides and automatically latches into position to engage the battery contacts on the bottom of the
instrument. The Li-ION battery is 7.4V nominal and connects directly to the instrument. This battery is
designed to provide over 3 hours operation following a full charge. When the battery is inserted, power
can be applied to the instrument. When the battery voltage is too low to power the instrument, it will turn
off and go to 0 volts. The battery can then be charged via the charging connector with the supplied
charger. Refer to Section 4 – Battery Charger for charging details.

2. INTRODUCTION
The PC Data Acquisition Software provides the user with a flexible, easy to use software package. The PC
Data Acquisition Software is used to acquire data from the instrument, store data to files on disk, and
display data graphically.
The PC Data Acquisition Software can modify spectroradiometer parameters, take spectral measurements,
and download spectral measurements from the on-board memory of the HR-1024i or HR-768i to files on
disk. The PC Data Acquisition Software allows data to be configured and stored to a file on disk when
taking a spectral measurement.
The software has a number of features that provide a great deal of flexibility for spectral data acquisition,
display, and storage:
•
•
•
•
•
•
Data files can be configured as SIG Files for use with PC Data Acquisition Software; SIG
Files are saved to disk and may read back into the PC Data Acquisition Software at a later
time for analysis.
Data files can be configured as user defined ASCII Files for export to other software
packages; ASCII format files cannot be read back into the PC Data Acquisition
Software at a later time.
Data files can be automatically created and given an incremental extension at the end of the
acquisition.
Data can be saved to a unique file name at the end of the acquisition.
New data may be acquired manually by clicking the mouse on a button or pressing a “hot
key”; or new data may be taken automatically using a configurable timer.
Spectral data may be displayed in one of two ways:
o “Single Graph” mode, which displays the Reference and Target Radiance on the left
Y-axis and the Percent Reflectance on the right Y-axis for a single measurement.
o “Multi Graph” mode, which displays the Reference Radiance, Target Radiance, or
Percent Reflectance of up to 24 measurements in one graph.
Several tools are built into the software that allow SIG format data files to be merged, re-sampled, or reprocessed automatically (see the Tools Menu description below.)
The Data Acquisition Software’s initial screen is shown below.

Section 3 – Operation
1. Setup
Battery Pack
To use the instrument, install a fully charged battery pack (see Section 4 – Battery Charger). This is done
by sliding a charged battery pack into the battery slot located on the bottom of the instrument. Push in far
enough to latch it in place. When in position 6 copper contacts on the battery pack come in contact with 6
mating contacts on the bottom of the instrument enabling the battery pack to power the instrument.
Instrument Power-on Time
When initially turned on the instrument displays its model number on the initial LCD screen. During this
initial power-on period the instrument is waiting for the thermal-electric coolers to reach operating
temperature before data collection can begin. This period lasts less than a minute and when complete the
“Ready” light on the control panel comes on.
Instrument Warm-up Time
For optimal performance, the instrument should initially be turned on for a period of approximately 15
minutes prior to first use. During this period, the instrument should be placed in the environment where
scanning will take place. This period allows the detector temperatures and other electronics to stabilize
before taking spectral data.
Instrument Orientation
The instrument should be setup with its cooling slots on the bottom oriented as close as possible to
vertical. Also the bottom of the instrument should be oriented away from the sun in order to maximize
internal heat dissipation.
Laser (Tripod or Hand-held)
A sighting laser is used to aid in aligning the instrument to the target to be measured. The reference or
sample (target) should be placed to completely fill the field of view of the instrument. The sighting laser
can be actuated by pressing the laser scan switch on the top of the instrument.

2. Connecting The Instrument To A Computer
Prior to downloading spectral data stored within the instrument, and prior to using the PC Data
Acquisition Software to directly acquire spectral data, the instrument must first be connected to a (physical
or virtual) port on a Windows PC. This connection can take place in one of two ways:
•
By physically connecting the PC’s USB connector to the instrument’s USB-B connector (on
the bottom plate) using a standard USB cable. Installation of special device drivers (supplied
with the instrument) on the Windows PC is required. See Appendix E – PC USB Device
Drivers for installation instructions.
•
By creating a Bluetooth “virtual” COM port connection between the computer and the
instrument. This option requires installation of third-party Bluetooth hardware and drivers
(not supplied with the instrument) on the Windows PC.

PDA Software Application – Detailed Usage
Introduction
The PDA Data Acquisition Software application is based on the interface and functionality of the HR-1024i PC
Data Acquisition Software for the HR-1024i spectroradiometer.
Data File Format
Data files are stored as plain text in the SIG format (See Appendix B – File Descriptions for information on SIG
format data files).
DATA FILE NAMING CONVENTION (AUTOSAVE)
When in AutoSave mode, the software automatically creates and saves SIG format data in files that are named
according to the template “HR.mmDDyy.CCCC.sig”, where:
•
•
•
•
The field HR is the literal string “HR”
The fields mm, DD, and yy are the current month, day, and year respectively as determined by the
PDA’s clock setting.
The field CCCC is the value of the AutoSave File Counter field as shown on the PDA application
main screen (see below).
The .sig filename extension identifies this as a SIG format spectral data file.
DATA FILE LOCATION
By default, the PDA application saves all SIG format data files to the folder \My Documents\HR1024i_Data\
folder on the PDA.
Startup
On the PDA press the On/Off button. The PDA application can be started by tapping the Start button in the
upper-left corner of the PDA power-on screen, and selecting the PDA program.

Operation
The Menu Bar for the PDA application is situated at the bottom of the window. There are 4 menu items on the
Menu Bar, named from left to right as “File”, “Graph”, and “Instrument”, and “Help”; and two large Command
Buttons on the top labeled “Reference” and “Target” (See below.)
The Graph Type text field just above the graph area displays which graph display (Radiance or Reflectance) is in
effect within the rectangular Graphing Area.
The AutoSave File Counter (Scan:0000 in the example above) displays the value of the counter that is used to
form the next AutoSave file name. The counter is incremented after each target acquisition while in AutoSave
mode. This counter may be used to tie together AutoSaved file names with notes taken regarding targets during field
acquisitions. By convention, the AutoSave file name has the format “HR.mmDDyy.XXXX.sig”, where XXXX is the
value of the AutoSave File Counter. Note that this counter displays the count of the next target acquisition,
not the currently displayed target acquisition.
The following sections describe these features in more detail.
COMMAND BUTTON “REFERENCE”
The “Reference” button is used to initiate a Reference scan acquisition by the instrument. The instrument must be
“connected” to the PDA for a successful scan to be acquired. Once the scan is acquired the Radiance result will be
displayed graphically if the graph is configured to display Radiance.
COMMAND BUTTON “TARGET”
The “TARGET” button is used to initiate a Reference scan acquisition by the instrument. The instrument must be
“connected” to the PDA for a successful scan to be acquired. Once the scan is acquired, the Radiance result will be
displayed graphically (if the Graph mode is set to display Radiance) or the Reflectance result will be displayed (if the
Graph mode is set to Reflectance). The acquired scan can then be saved to file manually, using the FILE>SAVE
menu, or it will be automatically be saved if the File->AutoSave option is checked.

PDA Power Up
If the PDA is turned off, or automatically powers down while the PDA application is in use, it may be
necessary to perform a Soft Reset on the PDA, followed by a restart the PDA application.
In general, after turning on the PDA and before beginning a series of new scans with the PDA application,
it is recommended that the operator always first perform a Soft Reset on the PDA.
PDA Charging
Even when not in use, the PDA should be periodically recharged every few weeks. This process allows the
PDA’s internal backup battery to maintain the PDA application installation and configuration.
Failure to maintain the charge on the PDA’s internal backup battery will cause the PDA application to be
lost. In this case the PDA application must be re-installed from the supplied CD.
PDA COM Ports And PDA Application Software
The PDA Application Software’s “Instrument->Connect” menu displays a list of COM ports that are
available to establish the connection to the instrument. A typical list, as displayed, is shown below:
The list of COM ports displayed in this dialog (COM1 and COM8 in the example above) may vary from
one PDA installation to another.
The COM ports shown in the dialog are read from the file named “HR1024i_INI.txt” in the PDA folder
“My Device\Program Files\Spectra Vista\” at program startup. See Appendix B – File Descriptions PDA
Software COM Port Configuration File for the format of this initialization file.
The COM1 port is typically fixed and corresponds to the 9-pin RS-232 connector found on the PDA.

Appendix K – Instrument Remote Access
GENERAL PROTOCOL DESCRIPTION
The PC Data Acquisition Program can act as the access point that will allow a customer to remotely control the
instrument from a custom software application. The access allows the customer's software to:
• trigger a reference, or target scan
• receive the results of a target scan
In order to control the instrument, the PC Data Acquisition Program acts as a network server. This network server
function listens for TCP/IP socket connections from the customer's (client) software. The customer's client
software sends trigger commands to the server, and receives responses and spectral data from the server.
Functionally, the operator first uses the PC Data Acquisition Program in the standard way - connect to the
instrument and set the desired scan parameters (Scan Time, Integration, Auto Dark, Optic, Overlap/Matching, etc).
Once the desired scan parameters are set, the operator causes the PC Data Acquisition Program to enter into its
“Remote Server” listening mode. At this point, the customer's client software is able to connect via a TCP/IP
network socket and remotely control the instrument.
See the description of the Remote Access Tool in Section 2 – PC Data Acquisition Software for specific controls
and descriptions on how to setup the PC Data Acquisition Software to act as a remote server.
DETAILED PROTOCOL DESCRIPTION
All the client/server communication uses simple human-readable ASCII commands and responses.
The client and server software may reside on the same (Windows) computer, or may reside on different computers
that are connected via a TCP/IP network.
The PC program accepts and responds to the following commands from remote clients that want to remotely
control the connected instrument:
Reference Scan Command
Command: "R" - This single character command triggers a reference scan acquisition in the instrument.
Normal Response: "r<cr><lf>" - This three character response is sent back to the client after the reference scan
is complete. The reference scan may take up to 1 minute to complete, depending on the instrument's current "Scan
Time" setting.
Error Responses: "E: Reference Scan Error<cr><lf>" - An error occurred while taking a reference scan. This
could be caused by a timeout or other communication error between the PC and the instrument.
Target Scan Command
Command: "T" - This single character command triggers a target scan acquisition in the instrument.
Normal Response: "t<cr><lf><SIG><Ctrl-Z>" - This response is sent back to the client after the target scan is
complete. The target scan may take up to 1 minute to complete, depending on the instrument's current "Scan Time"
setting. Following the normal three character response “t<cr><lf>”, the entire <SIG> format text file (containing

the last reference, target, and reflectance data) will be transmitted back to the client, followed by the single <CtrlZ> (end-of-file, ascii code 26) character. The <SIG> file will typically be somewhere between 32K and 64K
characters in length.
Note that the <SIG> format file itself has embedded <cr> and <lf> characters.
See Appendix B – File Descriptions Signature File Format for a complete description of <SIG> file formats.
Error Response: "E: Target Scan Error<cr><lf>" - An error occurred while taking a target scan. This could be
caused by a timeout or other communication error between the PC and the instrument.
Error Response: "E: Target SIG File Open Error" - An error occurred while attempting to open the SIG file in
preparation to sending the target data back to the client.
Unknown Commands
Command: <unknown> - an unrecognized command of some kind has been received by the server. The
command is not one of those listed above.
Error Response: "E: Unknown Command - <unknown><cr><lf>" - This response flags any unrecognized
command received by the server. The client should close down, and re-establish the socket connection in order to
recover from this error.
Busy Errors
If a new command is sent from the client before the previous command has completed, the server responds with an
“E: Busy<cr><lf>” message.

Appendix N – Fiber Optic Installation
The instrument’s fiber optic adapter installs the same way as the various foreoptic lenses. Similar to these lenses it
has a pin to set a constant clock angle with the instrument which is especially important when using the fiber optic
to maintain a stable radiometric calibration for correct data acquisition.
1.
Remove any foreoptic lens that is currently installed by turning the knurled retaining ring CLOCKWISE while
facing the instrument noting that the threads are right handed and the retaining ring has to move towards the
instrument.
2.
Orient the fiber optic adapter so that the clocking pin is face-up, as shown below: CAUTION – DO NOT
ALLOW ANY FOREIGN MATERIAL TO ENTER THE INSTRUMENT CAVITY AS IT MAY
INTERFERE WITH THE FIBER ADAPTER INSTALLATION, DAMAGE THE INTERNAL
OPTICS OR EFFECT THE INSTRUMENT’S RADIOMETRIC CALIBRATION.

Appendix O – Optional Fan Installation
WARNING: If the optional fan assembly is installed on the instrument’s heat sink, do not operate the
instrument unless the fans are actually turning and providing cooling air to the heat sink. Installing the
fan assembly onto the heat sink without running the fans can cause undesirable thermal effects on the
instrument.
